get. when to sow the seeds, and when to 
plant permanently out? (R. P. S., Essex.) 
Good varieties of Cabbage Lettuces for 
winter culture are All the Year Round and 
Hammersmith Hard}’ Green. You might 
have sown these in August, but a good plan 
would be to sow them in boxes now and as 
soon as the Tomatos are gathered the Let¬ 
tuces should be ready for planting out in 
the house. If. it had been in any way 
heated, it would not have been necessary 
to sow so early, but you should remember 
that this is now September, and Lettuce 
after this month will not make much pro¬ 
gress in two months’ time. You do not 
say whether there is any object in getting 
into the market even earlier than you state, 
but if the weather happened to be fine and 
warm during the incoming year, they would 
be ready for use before the time you state, 
but from the middle of November till well 
into January they will not make very much 
growth in a cold house. We are surprised 
that you should not have thought that Cos 
Lettuce would be even more serviceable and 
desired in the market. If you resolve to 
have Cos Lett-jce, then Black-seeded Bath 
or Hick’s Hardy White might be used. 
MISCELLANEOUS. 
2 203. Address of Secretary.

notice of a meeting of the Benfieldside and 
District Sweet Pea Society. I shall esteem 
it a favour if you can kindly furnish me 
with the name and address of the Secretary.

is Mr. C. F. Tait, 45, Cutler’s Hall Road,

NAMES OF PLANTS.

should send flowers as well. It cannot be 
determined from a leaf alone.—(Scottie, 
Dundee) 1, Aster Amellus; 2, Centaurea 
montana; 3, Delphinium grandiflorum pro¬ 
bably (send in flower); 4, Phlox paniculata

Common Insect Pests. 
Of the numerous insect pests gardeners 
have to contend against, probably wi; 
worms are to be most dreaded of all, be¬ 
cause they do not confine their attacks to 
the plants of a single -order and feed upon 
stems and roots at all seasons of the y ear. 
Trapping the larvae by burying pieces of 
Potato or Beetroot under the earth often 
proves successful. (Mark the spots with 
pegs, and examine them every few days, 
collecting and burning the baits. 
Another method of eradicating this pest 
is to apply fresh lime to the ground when 
trenching, which will destroy many of the 
wireworms. 
Slugs and snails are a source of aauch 
annoyance. A good remedy is to place 
some finely sifted ashes round the plants 
and along the rows of such crops as Peas. 
A mixture of lime and soot is often used, 
and is quite effective so long as it is dry, 
but when once wetted it is useless. 
The Celery Fly is another common pest 
which often damages the crop. The larvae 
feed upon the soft, juicy tissues of the 
leaves, which soon turn brown. All leaves 
so affected should be picked off and 
burned. The best preventive measure 
is to dust the plants over when wet with 
soot, as this will prevent the fly from de¬ 
positing its eggs upon the leaves. 
The Onion Fly often does much 
damage, completely ruining the whole 
crop. Dusting the plants over with soot 
is the best remedy. It is a good plan to 
sow Onions in boxes and prick them out, 
for plants raised in this way more fre¬ 
quently escape the pest than those sown 
in the seed bed. 
The Codlin Moth is annually the cause 
of the premature falling off of many -of 
our best Apples. When the larvae are 
hibernating in the bark, spraying the 
trees with caustic- alkali wash does much 
good in destroying them. The caterpillar 
can be trapped by fastening hay bands 
tightly round the trees in the early sum¬ 
mer. These should frequently be re¬ 
moved and burned. 
The Cherry Aphis can be eradicated by 
spraying the trees with quassia extract. 
This should be washed off with clear 
water the following day. Plum trees at¬ 
tacked by aphides may be sprayed with 
the same preparation. Green Fly under 
glass is best eradicated by vapourising 
with nicotine compound, while that on 
plants outside can be got rid of by spray¬ 
ing with quassia extract. 
Mealy Bug is very troublesome and 
difficult to exterminate. Syringe the affec¬ 
ted plants with paraffin and water, at the 
strength of a thumb-pot full of paraffin to 
three gallons of water. In some cases 
methylated spirits applied with a camel's 
hair brush is a good remedy. When 
greenhouse climbers are infested a thor¬ 
ough fumigation will destroy’ much of the 
pest. 
Red Spider is often troublesome, but if 
the syringe is liberally used and the house 
kept well damped the cultivator will have 
little to fear from its depredations.
